Simulationsmethoden im Brandschutz

und in der Gefahrenabwehr


On the application of CFD in fire safety
Between theory and practice or the user's role


Berlin, den August 2012

Simulation codes for Computational Fluid Dynamics (CFD) may be considered mature engineering tools today. They have stood the practicioners’ test of time and are routinely used in a supportive, sometimes central, role, e.g., in the shape design of airplanes or cars or for the layout of gas turbines and inter- nal combustion engines. Here, however, we are interested in their application in safety-critical contexts and this raises some more fundamental questions.

Furthermore, we present some examples showing in which way the user can influence the computed results. Using the well documented and freely available field model Fire Dynamics Simulator (FDS) we explain some critical numerical aspects of the implemented numerical scheme and discuss their importance for the user. We show, in particular, that trustable results require both well-tested programs and well-trained users.
